Ridgway Dam

Ridgway Dam is an earthen dam on the Uncompahgre River which impounds Ridgway Reservoir, located about 6 miles (10 km) north of the town of Ridgway in Ouray County, Colorado. The dam is 332 ft (101 m) high and 2,465 ft (751 m) long, with a capacity of 84,410 acre⋅ft (104,120,000 m3) of water.

Ridgway Dam was built as part of the Dallas Creek Project. Construction began in 1978 and completed in 1987. The construction of the dam forced the re-routing of U.S. Highway 550 to the east and the abandonment of the Ridgway Branch of the Denver and Rio Grande Western Railroad.
